perf(lexer): Use SIMD to accelerate whitespace skipping

[Boshen]

Sometime ago I drafted a version to use SIMD for skipping whitespaces:

In this good first issue, you should be able to replicate the code from above, and add it to the lexer.

You should refactor the code above into a function and call the function just above the while loop:

https://github.com/Boshen/oxc/blob/93993978de969589f1fb91a689594a5e5c4b8f02/crates/oxc_parser/src/lexer/mod.rs#L320-L330

You will also need to add #![feature(portable_simd)] to the top of crates/oxc_parser/src/lib.rs

To the run parser, you can run the example binary:
